You get a full set: top sheet, bottom sheet, and two pillowcases.
Promising review: "I cannot sleep comfortably without 100% cotton sheets and these have been wonderful. They are great quality especially considering how inexpensive they are. I got the blue and it's still vibrant and bright after two washes, and I have no complaints.
Also, FYI 100% cotton sheets will wrinkle, you will have to iron or steam them if this bothers you. You can take precautions to reduce it, like washing on the gentle cycle, or untwisting them before putting them in the dryer, but as a rule cotton wrinkles." —Belle
